In the following sequence of numbers, one number is the “odd man out.” That is, it doesn’t fit the pattern.
Can you find the number?
0, 4, 8, 12, 14, 20, 24

multiples of 4. The correct number at this place in the list is 16.
In each of the problems below, one number doesn’t fit.
Highlight the incorrect number and then identify the number that should be in its place. (2 pts)
Describe the pattern you see using words. (1 pt)
Write an explicit OR recursive formula for each sequence. (2 pts)
